METALLIZED POLYESTER

SERIES 1313

EFC Series 1313 are metallized polyester capacitors. This series offers the advantage of

small size, self healing and low cost. Suggested applications include: medical electronics,

telecommunications and high voltage power supplies. Packaging options include: wrap

and fill (TF, TC), radial lead box (EFR), axial lead (EC, EF). Application options include:

high voltage (HV), "AC" across the line (AC), noise suppression (RC) and switching power

supply (SP).

SPECIFICATIONS

1. TEMPERATURE RANGE

- 55 OC to + 85 OC at rated voltage.

To 125 OC at 50% derating.

2. CAPACITANCE

Capacitors < 1.0 MFD shall be measured

at 1 KHz + 20 HZ. Capacitors >1.0 MFD

shall be measured at 120 HZ. Measurements

shall be taken at 25 OC.

3. DIELECTRIC STRENGTH

At 25 OC, 150% of rated voltage when applied

terminal to terminal for one minute through a

current limiting resistance.

4. INSULATION RESISTANCE

At 25 OC after 2 minutes charge time at rated voltage

or 500 VDC, whichever is less, the minimum IR shall

be 30,000 Megohm-Microfarad, but need not exceed

50,000 Megohms for voltages greater than 50 VDC,

and 15,000 Megohm-Microfarads, but need not exceed

30,000 Megohms for 50 VDC or less.

5. HUMIDITY RESISTANCE

Series 1313 shall meet the requirements

of MIL-STD. 202C, Method 103B.

6. DISSIPATION FACTOR

Shall be 1.0 % max. when measured as in Par. 2.

7. LIFE TEST

Will withstand the application of 150% rated voltage at +125 0C for 250 hours

with not more than one failure in 12 permitted.
